" They had three cadences, these spectral drummers, which they called First Kings, Second Kings, and Revelations. Going into a fight, they went from one cadence to another with no apparent signal until the officers began to shout commands and men began to fall. Then the drummers began a solemn drill beat that Bushrod believed would be the muttering undertone of every nightmare he would ever have. "
